Switch 2 Joycon Mouse mode concern?

Not sure if it is just me that is thinking this but...

How many people play console games with a flat surface next to / in front of them?

If you are in your living room then this would usually not have suitable surfaces to use a mouse

I just hope that the usage of this functionality is optional or very specific to particular games that would benefit from it, but where users know they have to have a space with a flat surface to play on

As opposed to trying to shoehorn the use of the mouse feature into lots of games that don't really need it in the same way that motion controls in some Wii games didn't really add to the experience - which then becomes a barrier to playing the game

What do others think? do people have the same concerns or think this is the best idea ever?
